' TO ALL WHOM IT MAY CQNCERN: v Y

Be it known' that I, R.l M. BROOK-S, of Gridin, in the county of Spaulding, and in the Stoteof Georgia, have invented certain new ond useful Improvements in Railroad-Rail s; and do hereby declare that the following is a full, clear, and exact description thereof, reference ,being A had `to the accompdnying drawings, and to the letters of reference marked thereon. 4 ,I i v The nature o'f ,my invention consists in making u. railroad-bor in .two parts; one the bottom part, with n tongue in its centre to runinto, the groove Vou the hollmLbar. st onp, and. in hosting the iianges on the sides of the hollow bali-'oi' cap notched or corrugated, so as to t into 'similar notches or eorruvotions xn the flanges of the sides of the bottom part. This isfor the purpose ofimpar'ting additional-strength to the rail.

Toenableother's skilled in the art to mathe and use my invention, I will proceed to describe its construction and operation.

In the 'annexed drawings, forming part of this specification, A represents the bottom ruil, mode with n v tongue, C, in its centre`,' and its sides protected with izinges a a'. The insides of these flanges have series of notches or. corrugations out ingte Athem. B represents the-top rail or cap, which is made hollow to allow the tongueC, on the bottom rail A, to enter, and the flanges I1, projecting from the sides of this hollow top ruil or cap B, are also provided withl notches or c'orrugations, which, when the cup is put on the bottoiurail, fit into the notches already descri-bed as being on the bottom r`ail, which is shown in Figure 2. l

. By this arrangement the rails will be-rem'urka'bly strong, so much so, that if the notched rails were laid downs quarter of :n.mile on each side ofnnd on'a. bridge, they would be suiiiciently strong to hold np and support a. heavy .trninlif the arches ofthe bridge should by any accident give way, thus preventing disasterjand loss of life.

Having thus fully'descr-ibed my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination o f the railroad-rails A and B, provided with corrugatedienges a a and 6 b,ond fitting together, substantially as and for the purpose set forth. l

I n testimony that I claim the foregoing, I have hereunto' sel; my hond, this 2 2d day of'April, 1868.
